TYPEwEI'rING MACHINE.

Original application filed September 27, 1922, Serial No. 590,756. Divided and this application filed- July'V 23, 1925.

The present invention relates to sounddeadening casings for typewriting machines. A casing of this character has an Opening in the front thereof, through which the keyboard extension of the machine may project,

in the upper part thereoffor movement of the typewriter-carriage in letter-feed and return directions; and the upper partof the casing is slotted horizontally andlongitudi nally thereof, for projectiontherethrough,

` and for movement therealong, of the operat ing levers on the typewiitei.-carriage. j

The casing is usually made in two sections,

to wit, a'body-section, provided with` a suitable base-piece, and a cover-section, hinged thereto; the cover beingy opened for placement and removal of the machine. opening in the front ywall of the Vcasing for the keyboard extension may extend to the top of the casing-body; or-may not extend to the top of the casing-body, in which latter event the machine may be inserted into the casing, in tilted position, and the keyboard extension passed forward through the opening in Ithe front wall thereof. The shellsections ofthe casing have been provided with lining-sheets of soundfdeadening material, suoli as felt; and the joints thereof,at the openings or slots, through which project the keyboard andthe operating levers ofthe machine, have been equipped withV cushions or edgings, which close thesame against the emission' of sound `whenthe machine is in Y place; with-out, however, interfering with sion of a base-piece for `the casing, and .for

placement or removal of the machine, or with movement of the carriage and operating levers thereon.

A feature Of the invention is the provi- The' Serial No. 45,548.

When it is desired'toclean lthe casingof the dirt which may have accumulated from erasures and other sources, the pan `is removed and the dirt maybe brushed out` through the openingin thevbase.V

v,Figure 2 is a view, in cross-sectional side elevation, showing the mounting of the casing on` its base-piece.

Figure 3 is a top plan view of the casing,

the coverbeingbroken away to Vshow the interior of the casing-body. j

Figure 4 is a top plan view of the casing-` base-piece; the same being broken away at one corner to show the sound-deadening lining and supporting plate therefor.

The casing is in two principalparts, to.

wit, tbody-portion 10 and a cover 11; the cover being hinged at 12at the rear'thereof to the body-portion. -The rearffront, and

side walls of the casing-body are lined with4 sound-deadening material 13. -The front wallof the casing is cut away, as at 11, so' f that the keyboard extension 15 of the typewriting machine 16 may protrude thercthrough. j Forrsecuring the lining 13 to the sheet'- ing` 10 ofthe casing, th-e latterV has,staked v therein, bosses or bushings 17 which pass through openings in the lining, and which are threaded toreceive screws 18, which pass through retaining strapsr19 laid longitudinally of vtheJ inner face of the` lining, to "hold the straps'to the bushings `17. At its lower edges the sheeting 10 has a reinforcing bead Ilm 20 formed peripherally thereon; and, from of theflining 13 is setupon the flange'21;

` the bead 20, is turned inward toform a hori- A zontal peripheral flange 21. The lower edge reinforcement, serves as a seat for the casins proper Oe its base-pieve At the treat ef the casing-body the lining lf3 terminates with the sheeting at the sid-esV ot the.

opening 141er the keyboard extensipn. Eef low the keybarfd ertenien, the sheeting. 1.0 is continued, from side to side ot the casing,

as a slightly odset strip 10'nl (seehigure The piece 10a is lined with a sound-deadening strip f 23 held thereto by a strap 24, which is secured by screws 18?e to. bushings 17:L staked or riveted in the sheet-nietah The lining-strip 23, like the lining 113, is setupon the peripheral {ia-nge 21 of the casingLbody. The upper edge 'ot the liningo strip 23 is extended, as at' 23a, as a resilient tongue to engageand Vpress aoainst a rod Y26 on the machine when the latter isin place.

In order, to permit the casing tov clear said uppervcorn'ers of the deslr, and, nevertheless, to be supported upon the platform 36 located in a depressionin 5 the top ot the desk, a bolster or standard 38 (see Figure 1) in interposed between the flange 21, 'which forms the lower edge `oli the casing proper, and the casing-base-piecc This standard includes tivo U-shaped sheetlmetal members 40, having their ends set teg'ether at fil, to torni a "rectangular pieta?. lhe tivo members 40 are held to gether by plates 4 3, which overlap the joints 421, and which are riveted. as at to the U-shaped sections.

Washers 52@ of sumid-` deadening material are set between the screw-heads 5:3 and the Wooden plate 51. The assembled casing, bolster 3S and basepiece 39 are held toA the platform 36, and the machine anchored in the casino, by bolts 55, which have'their heads 56 set in recesses inthe bottom. ot the plat-form, and which pass upwardv through openings 57 in the base-piece 39,l through the bolster 38 and into the casing'proper, Where they thread at 57a into bosses 58 on the main trame ol? the machine. Tvl'her-r the bolster 33 is em" ployed, in use of the casing on a platform in the depression 'ot a desk, the usual short reet ofthe machine are replaced by longer ones 59.,` so that thefeetmay entend down through the top of the pan 49, to rest upon the sonnd-deadening material-5d and thus have the machine at elevationcorresponding With that of'v the casing. For locating the machine Within the casing, the pan 49. has circular, upvvardly-protruding .guards 60 turned out et the same, into which the `feet 59 are placed,

1f the casing is to be used on a desk Without a depression, the bolster 38 is not necessary., and thevcasing-body may be supported directly upon the base-piece 39, as shown inFigurel 2; that is to say, thelange 21 or' the casing proper may be set directly upon the pan 49. The screws 52 will, in this'instance, be shorter than the screws 52 shown in the Figure 1 struct-ure; and the feet 59 of the machine Will be of the ordinary height. The Wooden plate. 510i the hasepiec'e, Eigures 1 and-2, is shown as having pads or feet 61, ot'lfelt or other sound-deadening material, secured thereto, by screwsl 62, to prevent transmission otsound-vilnations from the-case'toits support.

In order that the casing, 'or casing a d standard, may be rcadily'clcancd et dirt,

from erasures and other sources, the basepiece 39 has an Iopening-61` therethrough, which is normally closedbyj a pan-like cover 65, having'` a peripheral flange (36by means of which it is supported on the inverted pan 19 of the base-piece. For easy removal oi the cover 6,5,thesame is provided with a Y handle. 67, p ivoted at 68 to bosses 69 on said cover, so that the handle may normally be set `down in Figure 1 position7 but may be swung up for removal of the cover.

Asv to the bolster-38- for elevating the casing for use of the same on al drop leaf, it will noted that the same is placeable and removable, at Will, between the' casing-body andthe baseepiece 39; on which latter the Inacliinev rests, Whether the standardl be present or-not. In other Words, the bolster need not be constructedV to support the Weight ofthe machine; and, in the absence a base-piece having a hole therethrough forv the removal oi':' dirt, a door for closing the hole, and means whereby the door may be opened from the interior of the casing.
